This is the set of questions that started this thread, but as a result of it, we have collected a lot of interesting and useful information on the LEDs available for the 159/Brera and as such, I have edited the original post to capture it for anyone who is interested to save them having to wade through the entire post!
I am going to split this into 3 parts
I Have installed the 8 SMD LED can-bus w5w's off eBay in the side lights on my 159 and 4 SMD LED can-bus one's in the number plate light. They look great and match the HIDS's I run perfectly. I am, however, interested if anyone has any suggestions for the H7 main beams to match? I have seen some 128 SMD LED can-bus ones on eBay but not sure if they are going to put out enough light. It's the 2.4 diesel so there is not much room behind the headlights to make the change, so want to be 100% sure before I even attempt the job as doing it twice will not be fun!!!!
I would also like to upgrade the indicator, and rear driving & brake lights to LEDs. Has anyone tried this, if so, what did you use and what was your experience? I have read differing views on this, so open to suggestions that are of course "constructive"!
I am also very keen to change all the interior and puddle lights to LED. The question is, how do you get into the units on the roof?? I have had a look and cant for the life of me figure out how to open them to get to the bulbs!! Puddle are easy, w5w's accessed with a screwdriver for leverage, but before i tear a hole in my roof lining I would appreciate some advice from someone who actually knows how to open the units (front and rear pods).
Clearly, you can see I am obsessed with LEDs. I know, its strange, but I think they look good for two reasons, 1) the illuminate instantly, without the milliseconds of delay a filament has and 2) they have a much richer/deeper colour, both of which points make them an attractive, and potentially easy upgrade for my car. - I would therefore rather not turn this into a debate on taste and rather refer to prior experience or advice on any of the 3 points above
So here is what we have established:
Autobulbs Direct have a great lighting guide that lets you select the exact model variant of your car and see what the bulbs are for each area here
so always check before you buy, but as a rough guide:
The 159 is typically:
Dipped Beam H7
Main Beam H7 (Not H1 as listed)
Front Fog H1
Front Indicator 581
Rear Indicator 581
Number Plate 501
Rear Fog 382
Interior Maps 501
Interior Mains 43mm Festoon
Boot 43mm Festoon
The LEDS should always be CANBUS type LEDs or the car will get upset and either constantly show you annoying bulb blown errors or do stranger things like never actually switch off the light!
LED's are very cheap, which is reflected in their manufacturing, so always buy a spare set as they may turn up faulty (examples include some of the LED's on the bulb not lighting up or CANBUS errors)
If your going to have a go at the interior lights, fog lights or any light unit that requires you to pry some trim away from the car, you would be wise to invest in a set of Bojo bars! They are essentially plastic/nylon crowbars designed to remove trim without breaking it. You can pick up a full set on ebay
for around £25 and they are a sound investment.
If your going to replace any of the bulbs in the headlights, your going to draw blood and/or loose skin off your hands unless you invest in a pair of workout / training / weight lifting gloves to protect the fleshy bits while leaving your fingers free to do the fiddly bit!

Common Front Sidelight replacement options:
Option 1 Lights
A new LED option for sidelights has become available as discovered by AndyB2801:
These units give a clear bright white light that is ideal to match the HID's. Pictures can be found in Post 692
Option 2 Lights 8LED
8 LED CANBUS w5w (501) type bulbs
These offer a good balance of light into the reflector housing and light thrown forward, and are the whitest we have found at about 4000K to 5000K.
Option 3(new as of 15/11/2011)
2 CANBUS LED BULB xenon white SIDELIGHT 501 W5W T10 SMD
These new options are a 24 LED set-up which offer a great mix of light thrown both forward and into the reflector. They are about 6000K in colour so match HID's well. The caveat here is that the round bit that holds the LEDs at the front is factionally to wide to go in the light so you need to use a fine sand paper, wetNdry paper or knife sharpening block to take about 0.1/0.2mm off the diameter before they will fit. Only takes a couple of minutes, honest!
WARNING: some of the people who have tried these have experienced canbus issues (myself included). To solve these issues you need to make a small modification to the bulb units in order to fix them. Credit to AwB
for this fix:
1) Purchase 2 x 330 ohm resistors from somewhere like Maplin's
, for around 24p each.
2) Solder the resistor across the terminals. NB, you can just poke the ends through the holes and rely on the compression it will then get once inserted into the bulb holder if your not proficient with a soldering iron!!
3) Insert bulbs back into the car - Can Bus erros sorted!
NB: for sidelights you want to put as much light into the reflector housing as possible or you defeat the object of being seen rather than lighting the way ahead.
Numberplate light replacement:
4 LED CANBUS w5w (501) type bulbs
NB: The number plate light housing does not have a reflector in it so using a LED type that has bulbs pointing the way you want the light to go is important. Also, you dot want these to be so bright they dazzle the cars behind you, hence the 4 LED options.
